Ast month when Holiday Creations Inc. Sold $50,000 units, total sales were $200,000. Total variable costs were $120,000 and tota

Zielflug [23.3K]

Answer:

40%

Step-by-step explanation:

The first step is to calculate the unit selling price

= total sales/number of units

= 200,000/50,000

= $4

The unit variable expense can be calculated as follows.

= total variable expense/number of units

= 120,000/50,000

= $2.4

The contribution margin per unit can be calculated as follows

=selling price per unit- variable cost.

= $4-$2.4

= $1.6

Therefore the contribution margin ratio can be calculated as follows.

= $1.6/$4

= 0.4×100

= 40%

Lavania is studying the growth of a population of fruit flies in her laboratory. After 6 days she had nine more than five times

MatroZZZ [7]

Answer:

Lavania observed 39 fruit flies after 6 days of observation

Step-by-step explanation:

Let x be the number of fruit flies on the first day of Lavania's study.

After 6 days she had nine more than five times as many fruit flies as when she began the study.

Five times as many fruit flies as when she began the study = 5x

Nine more than five times as many fruit flies as when she began the study=5x+9

The expression to find the population of fruit flies Lavania observed after 6 days is 5x+9

If she observes 20 fruit flies on the first day of the study, then x=6, then

$5x+9=5\cdot 6+9=30+9=39$

-3+ 4d - 2f + 3d + 6f - 4 - 8

Igoryamba

Answer:

Explanation:

-3 + 4d - 2f + 3d + 6f - 4 - 8

= −3 + 4d + −2f + 3d + 6f + −4 + −8

Combine Like Terms

= −3 + 4d + −2f + 3d + 6f + −4 + −8

(4d + 3d) + (−2f + 6f) + (−3 + −4 + −8)

7d + 4f + −15

= 7d + 4f - 15

Find the volume of a cylinder with a radius of 3cm and a height of 7 cm.

svetoff [14.1K]

Answer:

The volume of the cylinder ≅ 197.82 $cm^{2}$

Step-by-step explanation:

The volume of a cylinder is equal to the area of the base times the height. We know the radius, therefore we can find the area of the base. The formula for the volume of the cylinder is as follows:

V = π $r^{2}$ $h$

(now substitute the values of "r" and "h", and get...)

V = π $r^{2}$ $h$

$V = (3^{2} )(7)$ x π

V = (9)(7)π

V = 63π

V ≅ 197.82 $cm^{2}$
